I plan on picking up a gintani hfc x pipe to go with my gintani sport and know I will get the CEL. I'm debating over picking up an akra delete r or going all out and getting an ESS tune. However, I don't want to void the lease warranty on my car (even though I plan on buying it out) nor would I want to void the manufacture or extended warranty after my buy out.

Basically, can I get a tune and not void warranty if i dont 1) remove the cold start, 2) extend the rev limiter, and 3) extend the speed limiter.
Now if I do do this, do I still gain all the power from a tune?

If I go with the delete, will the power gains from just the xpipe to enough to settle my crave for more power? If I do go the delete route, I'll use the extra $$ and get a gintani pulley while I'm at it.

Im worried about the tune and warranty but as for the xpipe, its a bolt on right? So, if anything I can swap back to my OEM pipes.
Basically then, will the power boost from the x pipe and maybe pulleys be enough? If down the line I decide I want more power I can do a tune .

In my opinion, your relationship with your service advisor and the relationship between you or them with the techs in the back (especially the foreman) is most important if you are truly worried about warranty issues.

Agreed, but they don't have control regarding warranty with big-ticket items. A regional supervisor will come out to assess the issue, at that point the tech and SA won't be able to help much. Not to be a downer, and I'm obviously all for modding, but I think it is important to know what you'll be dealing with if the shit hits the fan.

That is true and hopefully nothing major happens. But damn do they help on all the small stuff

None of those three things will improve performance... well perhaps the rev limit increase but I dont think it would be worth it.

I read somewhere that these 3 things were dead give aways of a tune. I just wanted to know though if they were essential to help towards the overall gains a tune is suppose to make

Ahh alright. I guess I'll avoid the tune for now. Maybe later on down the road. I'll stick to either cosmetics or the x pipe and delete

Like stated before the xpipe is more risky than the tune. I wouldn't stress about a tune but depending on the dealership the xpipe might cause you issues. If you get the xpipe definitely get the tune. The delete r isn't super cheap anyway...

Damn... I thought that since the xpipe is a blot on, wouldn't it only affect my warranty for just the x pipe section? also, with any problems, I'll keep my oem and if anything swap them. The tune to me was a bit more tricky to take out. Guess I'm wrong :

If you don't mind removing and reinstalling the x-pipe, tune, air filter and pulley when the car goes in for service, do those mods. Figure on 4 hours off and 4 hours back on for a DIYer for all those parts. If the car goes in once a year for an oil change, this might not be too big of a time commitment.

Skip the higher rpm limit and top speed delimit. The rpm and speed are stored in the computer and cannot be erased so BMW can find evidence of a tune if they spend the time to investigate. They will if you need engine work.

K I got a tune guys. It comes in today and hopefully I'll get it all set up. My only question is, is the removal of cold start really that noticeable? I know about don't mod if you don't want to void but I'm just asking.
I have no need for rev increase or speed limiter increase. I just want the extra hp and torque and the idea of no drone at start up is nice

It is noticeable but nothing that I have ever seen a tech at a dealer make a big deal about, but then again you never know.

Remember with the personal tuner you can always go back to stock before bringing your car into the dealer
